A BY

United States Pa ien My invention relates to combined sp'raying'ahdcleaningapparatus for 'cleaningipaifitandwhitewash'ofl buildings,especially barns, and repainting or whitewashing the same.

Theaprimar'y object' of .myinvention is to -provide efficient portableapparatus for quickly removingold paint or whitewash from such buildingsand spraying on fresh paint or whitewash evenly and which is readilyconvertible for .either of such uses and, will save time and laborandpaint'or whitewash.

Anotherobject is tovprovidesapparatus forthe above purposes which willmaintain paint or whitewash thoroughly mixed to preven t clogging of theapparatus during spraying, is not liable to get out of order and isinexpensive to manufacture, use and service.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming a part hereof, whereinlike numerals refer to like parts throughout, and in which:

Figure 7 is an enlarged fragmentary view in vertical section taken onthe line 7-7 of Figure 6;

Figure 8 is a fragmentary view in perspective of an air brush head foruse in converting the apparatus for cleaning; and

Figure 9 is an enlarged View in horizontal section taken on the line 9-9of Figure 8.

Referring to the drawings by numerals my improved apparatus comprises anoblong rectangular base panel 1 having suitably fixed on one end thereofa cylindrical open top supply and mixing tank 3 for liquid paint orwhitewash and which is provided in its bottom portion 5 with avertically pivotally oscillating strainer and mixer member designatedgenerally by the numeral 7.

The strainer and mixer member 7 comprises a cylindrical screen 9 ofsuitable mesh wire extending transversely in the tank 1 and closed atits ends by front and rear end disks 11, 13 connected together by rods15 spaced circumferentially around and supporting the screen 9 andmortised into the disks 11, 13. Conventional split ring clamps 17surround the screen 9 and disks 11, 13 and secure the screen 9 in place.

The strainer and mixer member 7 is swingably mount- 7 2,898,093.Patented Aug. 4, 1959 ed for vertical oscillation by meansof a flexiblehose section 21 connected at one end by a hose clamp 23 to an axialdischarge nipple 25 in the-front disk 11, said hose section 21 beingconnected at its other end by a hose clamp 27 to a liquid discharge pipe29 extending out of the' bottom portion 5 and one side-of the tank 3through a packing gland 31 in said tank. The" member 7 is oscillated bymeanspresently described.

When the apparatus is used for spraying the liquid paint or whitewashdesignated 33 is drawn from the tank 3 through the strainer and mixingmember 7 by means of a conventional pump 35 suitably fixed on the panel1, at one side thereof and in front of the tank 3, and a suction hosesection 37 detachably connected by hose clamps 39, 41 to the dischargepipe 29 and. to the intake side of the pump, respectively. The .pump 35forces the liquid through a pressure discharge hose line 43. connectedat one end by a hose. clamp 45' 'to the output side 47 of the pump 35and' terminating in an elongated spray 'nozzle 49 detachably connectedby a coupling '51 to a tubular handle 53 coupled to thepressu'redischarge line 43 by a conventional coupling 55. 'Thespray nozzle 49 islongitudinally curved for convenient .manipulation as shown inFigu'r'e 6and terminally perforated as shown in Figure 7. v

The means for oscillating the strainer and mixing memher 7 comprises apitman 57 including a peripherally grooved crank disk 59 rotatable on ahorizontal shaft 61 on an upstanding bracket 63 bolted as at 65 on thebase panel 1, said disk 59 having a vertical pitman rod 67 terminallypivoted as at 69 thereto. The pitman 57 is operatively connected to saidmember 7 by means of a transverse vertically rocker lever 71 extendinginto the upper portion of the tank 1 and pivoted, as at 73, to saidtank, said lever 71 being terminally connected at one end to said member7 by a link 75 pivoted as at 77 to said lever, and pivoted as at 79 to ahook 81 on the rear end disk 13 of said member 7, said lever 71 havingthe pitman rod 67 pivoted as at 83 to its other end.

Power means is provided for driving the pump 35 and the crank disk 59simultaneously comprising a conventional internal combustion engine 85suitably fixed on the base panel 1 a conventional reduction drive 87 towhich said engine 85 is operatively connected as at 89,

a belt and pulley drive 91 from the reduction gear drive 87 to said pump35 and a belt and pulley drive 93 from said reduction drive 87, the belt95 of which is trained around the crank disk 59.

For cleaning purposes a brush 97 is provided comprising a back 99 havinga manifold air duct 101 and air discharge ducts 103 in said back leadingfrom said manifold duct into bristles 105 on one side of said back 99. Atubular shank 107 is threaded at one end as at 109 in the other side ofsaid back into communication with the manifold duct '101 and is providedwith threads 11-1 on its other end for coupling the same to the handle53 when the spray nozzle 49 is detached whereby to convert the apparatusfor use for cleaning purposes in a manner presently more fullydescribed.

When the apparatus is converted for cleaning use by detaching the spraynozzle 49 and attaching the air brush 97 the suction hose section 37 isdetached from the pump 35 and suitably plugged so that with the engine85 operating the pump 87 atmospheric air is' pumped by said pump throughthe pressure discharge hose line 43 and brush head 97 and bristles 105so that said brush 97) may be manipulated to brush loose paint andwhitewash ofI' a building and blow such paint or whitewash away. I

The apparatus is converted for use as a sprayer by replacing the spraynozzle 49 and reconnecting the suction hose section 37 to the pump. Whenthus converted and the engine 85 running the strainer and mixer member 7is oscillated vertically by the described pitman 59, lever 71 and link75, as shown in broken and full lines in Figure 3. This agitates andstrains the paint or whitewash 33 in the tank 3 to blend and thereby mixthe ingredients thereof and prevent sediment from settling in the tank 3and passing into the suction hose section, the pump 35 and pressuredischarge hose line 43 and clogging the same and the spray nozzle 49. Atthe same time the paint or Whitewash 33 is drawn through the strainerand mixer 7 and through the hose section 37 by the pump 35 and forcedout of the spray nozzle in spray form for application to a building.

When the apparatus is being used for cleaning purposes the strainer andmixing member 7 oscillates idly to agitate and strain paint or whitewashif such be in thetank 3.

The suction hose section 37 may be left attached to the pump 35 when theapparatus is used for cleaning and the tank 3 is empty of paint orwhitewash and the atmospheric air drawn by the pump through the tank 3and the strainer and mixing member to issue out of the pressuredischarge hose line 43 and the air brush 97. In this connection it is tobe noted that the air brush back 99 functions in cleaning as a multipledischarge port air blast nozzle.

- The foregoing is considered as illustrative only of the principles ofthe invention. Further, since numerous modifications and changes willreadily occur to those 4 skilled in the art, it is not desired to limitthe invention to the exact construction and operation shown anddescribed, and accordingly all suitable modifications and equivalentsmay be resorted to, falling within the scope of the invention asclaimed.

What is claimed as new is as follows:

1. In apparatus for applying fluid spray to objects, an open top fluidcontaining tank having a fluid discharge suction pipe at its bottom andone side thereof, a foraminous hollow fluid strainer and mixer member inthe bottom of said tank, a fluid suction hose communicating with theinterior of said member and connecting said member to said dischargepipe in communication therewith, said suction hose providing forvertical oscillation of the member bodily in said tank, a rocker leverpivoted on the upper portion of the tank, operating connections betweensaid lever and member for oscillating the member in response to rockingof the lever, and power means for rocking said lever.

2. The combination of claim 1, said member comprising a foraminouscylinder having opposite ends, and said flexible hose connected to oneend thereof, said operating connections being connected to the other endof the cylinder.
